Invoice channels and requirements

How to submit an invoice

Invoices to ExxonMobil are accepted in different forms. 

For services and purchase orders via GEP Service Confirmation or Self-Billing / Evaluated Receipt Settlement (ERS):

• If you are already registered, you may continue to submit invoices using these methods. 
• If you would like to register, please contact gep.central.supplier.onboarding@exxonmobil.com. 

Email invoices

Invoices may be submitted via the e-mail address listed in the payables supplier kits (see below). 

• Note that email addresses may differ depending on the affiliate/country where you are sending the invoice.
• These e-mail addresses are used only to receive invoices; other inquiries sent to these mailboxes will not be monitored. 

You can check payment status or submit payment-related questions via the GEP Payment Status Tool at www.payment-advice.com. 

Important:

• Send only one invoice per e-mail. Any support documentation that you need to send with the invoice should be a separate file named Attachment.
• Invoice must not be encrypted or require a password to access. Special instructions submitted in the e-mail will not be monitored.
• Invoices must comply with the minimum invoice requirements described below. Invoices with missing or incorrect information may be returned to the supplier.
• When submitting invoices from purchase orders, it is recommended to submit a separate invoice for each purchase order to support fast and accurate payment processing.
• To submit invoices to ExxonMobil, you must have a vendor account. Please ask your ExxonMobil contact to ensure your account is created and up to date prior to submitting invoices
